Determining who really owns a business is often far more difficult than reviewing a company registration document. Modern ownership structures frequently include multiple holding companies, trusts, foundations, nominee shareholders, and entities spread across several jurisdictions.
For compliance teams, accountants, law firms, banks, fintechs, and regulated businesses, identifying Ultimate Beneficial Owners (UBOs) is a critical part of Know Your Business (KYB) and Anti-Money Laundering (AML) compliance. Failure to identify beneficial owners can expose organizations to sanctions breaches, money laundering risks, fraud, and regulatory penalties.
According to the United Nations Office on Drugs and Crime (UNODC), an estimated 2–5% of global GDP is laundered each year, highlighting the importance of transparency around business ownership.
This guide explains how to identify UBOs in complex ownership structures, common challenges encountered during investigations, and the best practices compliance teams use to uncover true ownership and control.

What Is an Ultimate Beneficial Owner (UBO)?
An Ultimate Beneficial Owner (UBO) is the natural person who ultimately owns, benefits from, or exercises significant control over a business entity, whether directly through share ownership or indirectly through a complex ownership structure. In AML and KYB compliance, UBO identification is essential because the legal owner listed on corporate records may not be the individual who truly controls the organization.
While legal ownership may appear under the name of a company, trust, foundation, or nominee arrangement, regulators require organizations to identify the individuals who ultimately benefit from ownership or exercise control. Effective UBO verification and beneficial ownership checks help prevent money laundering, financial crime, sanctions evasion, and fraud.

Understanding Ownership vs Control in UBO Identification
One of the most important concepts in beneficial ownership identification is understanding the difference between ownership and control. While many organizations focus on shareholding percentages, regulators increasingly expect businesses to identify the individuals who ultimately exercise influence over a company, even when they do not appear as direct owners.
For effective UBO compliance, both ownership structures and control relationships must be examined during Know Your Business (KYB), Customer Due Diligence (CDD), and Anti-Money Laundering (AML) checks.
Ownership Test
The ownership test focuses on individuals who directly or indirectly own a specified percentage of a company's shares, voting rights, or economic interests.
Most AML regulations require organizations to trace ownership through every layer of a corporate ownership structure until the natural persons behind the entity are identified. This process is often referred to as ownership structure mapping or beneficial ownership tracing.
Common thresholds include:
Jurisdiction | Typical Threshold |
EU | 25%+ |
UK | 25%+ |
Many AML frameworks | 25%+ |
High-risk investigations | Any significant ownership |
Example of the Ownership Test
Suppose:
- Sarah owns 60% of Holding Company A
- Holding Company A owns 80% of Operating Company B
Sarah's indirect ownership in Operating Company B would be:
60% × 80% = 48%
Because her indirect ownership exceeds the 25% threshold, she would typically qualify as an Ultimate Beneficial Owner (UBO).
When conducting beneficial ownership checks, compliance teams must continue tracing ownership chains until all qualifying individuals are identified.
Control Test
Ownership alone does not always reveal the true UBO.
In many cases, an individual may exercise significant influence over a company without holding a large ownership stake. Regulators therefore require organizations to assess who controls the business, not just who owns it.
An individual may qualify as a UBO if they:
- Control board appointments
- Exercise significant influence
- Hold veto rights
- Control trusts or foundations
- Direct business operations
- Influence major financial decisions
- Possess special voting rights
- Control shareholder agreements
- Act through nominee shareholders or nominee directors
Examples of Control Without Ownership
A person may be considered a beneficial owner even if they own little or no equity when they:
- Have the authority to appoint or remove directors
- Control strategic business decisions
- Manage trust assets on behalf of beneficiaries
- Exercise influence through contractual arrangements
- Hold powers granted under foundation or trust structures
For example, a founder who has transferred shares but retains veto rights over major corporate decisions may still be considered a UBO because of their continuing control.

Step-by-Step Process for Identifying UBOs in Complex Structures
Identifying ultimate beneficial owners (UBOs) in complex ownership structures requires a systematic approach that combines beneficial ownership identification, ownership structure mapping, and UBO due diligence.
The following steps will help compliance teams trace ownership chains, verify controlling individuals, and meet AML and KYB UBO compliance requirements.
Step 1: Gather Basic Company Information
Begin the UBO identification process by collecting essential corporate records that provide visibility into the company's ownership and governance structure. Key documents typically include company registration certificates, articles of association, shareholder registers, director registers, beneficial ownership declarations, and organizational charts. These records form the foundation for beneficial ownership identification and help compliance teams understand how the business is structured.
Where available, verify information against official company registries and beneficial ownership registers. Accurate documentation at this stage supports effective KYB checks, AML compliance, and ownership structure mapping, reducing the risk of overlooking hidden ownership interests.
Step 2: Identify Direct Shareholders and Owners
Review the shareholder register and related corporate records to identify all direct shareholders, members, or owners of the company. Record ownership percentages, voting rights, and any special share classes that may grant additional control. Both individual and corporate shareholders should be documented as part of the UBO due diligence process.
Pay close attention to corporate shareholders, as they often indicate additional ownership layers that must be investigated. Understanding direct ownership is a critical step in determining who may qualify as an Ultimate Beneficial Owner (UBO) under applicable AML and KYB regulations.
Step 3: Trace Ownership Through Each Layer
When a shareholder is another legal entity, continue tracing the ownership chain through every level of the corporate ownership structure. This process involves identifying the owners of each intermediary company until the natural persons who ultimately own or control the business are revealed.
Complex structures may involve holding companies, offshore entities, trusts, foundations, or nominee arrangements. Thorough ownership structure mapping helps uncover hidden beneficial owners and ensures compliance with beneficial ownership transparency requirements.
Step 4: Assess Control Beyond Ownership
UBO identification is not limited to share ownership alone. Compliance teams must also evaluate whether any individuals exercise significant control over the company through voting agreements, board appointment rights, veto powers, management authority, or other mechanisms that influence decision-making.
An individual may qualify as a UBO even without meeting the standard ownership threshold if they have the ability to direct the company's activities or exert significant influence. Assessing both ownership and control provides a more complete picture of beneficial ownership and strengthens AML beneficial ownership checks.
Step 5: Investigate Trusts, Foundations, and Nominee Arrangements
Complex ownership structures often involve trusts, foundations, or nominee arrangements that can obscure the identity of the Ultimate Beneficial Owner (UBO). To identify UBOs accurately, investigate all relevant parties, including settlors, trustees, beneficiaries, protectors, founders, nominee shareholders, and nominee directors. The goal is to determine who ultimately benefits from or exercises control over the entity.
Pay close attention to control mechanisms that may not be immediately visible in corporate records. Review trust deeds, foundation charters, nominee agreements, and other supporting documentation to uncover beneficial ownership and ensure AML beneficial ownership requirements are met.
Step 6: Verify UBO Information
Once potential UBOs have been identified, verify their ownership and control information using reliable and independent sources. This may include government registries, official corporate filings, beneficial ownership registers, commercial databases, and documentation supplied during the KYB process.
UBO verification should confirm both the identity of the individual and the legitimacy of their ownership interest or controlling influence. Independent verification helps reduce fraud risk, improves beneficial ownership transparency, and strengthens overall UBO compliance efforts.
Step 7: Conduct AML and Risk Screening
After verifying beneficial owners, conduct comprehensive AML screening to assess potential compliance risks. Screen all identified UBOs against sanctions lists, politically exposed person (PEP) databases, watchlists, and adverse media sources to identify any indicators of financial crime, corruption, or regulatory exposure.
Risk screening should form part of a broader UBO due diligence process. Any sanctions matches, PEP relationships, or negative media findings should be reviewed carefully and may require Enhanced Due Diligence (EDD) before onboarding or continuing the business relationship.

Step 8: Document Findings and Maintain Records
Document every stage of the beneficial ownership identification process. Create ownership structure maps, retain supporting evidence, record verification activities, and maintain detailed risk assessments for each customer.
A well-documented audit trail demonstrates compliance with AML and KYB requirements and enables organizations to respond efficiently to regulatory reviews, audits, or internal investigations. Accurate recordkeeping is a critical component of effective UBO identification and business ownership verification.
Step 9: Perform Ongoing Monitoring
UBO identification is not a one-time exercise. Ownership structures, controlling interests, and risk profiles can change over time, making ongoing monitoring essential for maintaining compliance.
Regularly review ownership structures and monitor for changes in shareholders, directors, controllers, sanctions status, adverse media exposure, or other risk indicators. Continuous monitoring helps organizations detect emerging risks early and ensures beneficial ownership information remains accurate throughout the customer lifecycle.

Common UBO Identification Red Flags
Recognizing common UBO identification red flags helps compliance teams uncover hidden ownership risks and strengthen AML and KYB processes.
The following warning signs can indicate challenges with beneficial ownership identification, UBO verification, and ownership structure transparency.
Frequent Ownership Changes
Rapid ownership transfers can be a significant red flag during UBO identification and beneficial ownership checks. When shares are repeatedly transferred between individuals, companies, or trusts within a short period, it may indicate attempts to conceal the true Ultimate Beneficial Owner (UBO), avoid regulatory scrutiny, or obscure links to high-risk individuals. Compliance teams should investigate the reasons behind ownership changes, review supporting documentation, and assess whether the transfers align with legitimate business activities.
Multiple Offshore Layers
Complex corporate ownership structures involving multiple offshore entities can make beneficial ownership identification considerably more challenging. While offshore companies are not inherently suspicious, excessive layers across different jurisdictions may reduce transparency and hinder efforts to identify UBOs. Organizations should carefully trace the ownership chain through each entity, verify ownership records independently, and apply enhanced due diligence (EDD) when structures appear unnecessarily complicated or involve high-risk jurisdictions.
Nominee Shareholders
Nominee shareholders and nominee directors are commonly used for privacy and administrative purposes, but they can also obscure the identity of the true beneficial owner. Because the individual listed on official records may not be the person exercising actual ownership or control, compliance professionals should investigate underlying agreements, declarations of trust, and control arrangements. Effective UBO verification requires determining who ultimately benefits from and controls the business.
Unclear Beneficiary Information
Incomplete, inconsistent, or missing beneficiary information is a major concern in trust ownership and foundation ownership structures. If beneficiaries cannot be clearly identified, organizations may struggle to satisfy AML beneficial ownership requirements and KYB UBO checks. Enhanced due diligence should be triggered whenever beneficiary details are unclear, unavailable, or appear intentionally withheld. Additional documentation and independent verification may be necessary to establish transparency.
Sanctions or Adverse Media Hits
When UBOs, shareholders, directors, or controllers generate sanctions screening, PEP screening, or adverse media screening alerts, additional investigation is essential. A sanctions match may indicate legal or regulatory restrictions, while adverse media can reveal allegations of fraud, corruption, money laundering, or other financial crimes. Compliance teams should assess the severity of the findings, document their risk assessment, and determine whether ongoing monitoring or enhanced due diligence is required before proceeding with onboarding or maintaining the business relationship.
